Open Pit Mining

Open-pit mining, also known as surface mining, is a surface mining technique for extracting rocks or minerals from the earth from large open pits. Generally, mining methods like this are more effective in relatively flat areas. The relatively sloping ground surface makes it easier for experts to carry out observations and evaluations more easily.

Coal Hauling

Once the production process is complete, the coal is ready for the next stage: transportation and sales. Transporting coal (coal hauling) from the mine location (pit) to the stockpile or directly to the processing unit. Transportation is a mining business activity to move minerals and/or coal from mining areas and/or processing and refining places to delivery places.

Coal Barging

Loading coal on a ship is called barging, which is the process of loading coal products that are ready for sale onto a barge to be transported to a predetermined place.

Coal from stockpile PT. Allied Indo Coal Jaya is sent to customers using transport trucks to Telur Bayur Port in Padang City which is around 103 KM and can be reached in approximately 3 hours.
